var orientation =  screen.msOrientation || (screen.orientation || screen.mozOrientation || {}).type;

if (orientation === "landscape-primary") {
  console.log("That looks good.");
} else if (orientation === "landscape-secondary") {
  console.log("Mmmh... the screen is upside down!");
} else if (orientation === "portrait-secondary" || orientation === "portrait-primary") {
  console.log("Mmmh... you should rotate your device to landscape");
} else if (orientation === undefined) {
 console.log("The orientation API isn't supported in this browser :(");
